Everyone:
This small series adds a driver for UCS1002 Programmable USB Port

and [datasheet] for device dataseet. Hopefully each individual patch
is self explanatory.
Note that this series is a revival of the upstreaming effort
When we fail from allocating inode/space, we back out

Currently the error return path from kobject_init_and_add() is not
followed by a call to kobject_put() - which means we are leaking the

The current kernel driver does not consider I2C_IPGCLK_SEL (424 bit
of RCW) in deciding i2c_clk_rate in function i2c_imx_set_clk()

When using ls1046a SoC, this populates incorrect value in IBFD register

For NXP ls1046a SoC, the i2c clock needs to be configured with the
appropriate bit of RCW, so we add the guts node (GUTS/DCFG global
utilities block) for the driver to read.

In an attempt to make the SMO patchset as non-invasive as possible add a
config option CONFIG_DCACHE_SMO (under "Memory Management options") for
enabling SMO for the DCACHE. Whithout this option dcache constructor is
used but no other code is built in, with this option enabled slab

In order to support object migration on the dentry cache we need to have
a determined object state at all times. Without a constructor the object
would have a random state after allocation.
Provide a dentry constructor.

We have just implemented Slab Movable Objects (object migration).
Currently object migration is used to defrag a cache. On NUMA systems
it would be nice to be able to control the source and destination nodes
when moving objects.
Add CONFIG_SMO_NODE to guard this feature. CONFIG_SMO_NODE depends
We have just implemented Slab Movable Objects (SMO). On NUMA systems
slabs can become unbalanced i.e. many slabs on one node while other
nodes have few slabs. Using SMO we can balance the slabs across all
the nodes.
The algorithm used is as follows:
1. Move all objects to node 0 (this has the
The dentry slab cache is susceptible to internal fragmentation. Now
that we have Slab Movable Objects we can attempt to defragment the
dcache. Dentry objects are inherently _not_ relocatable however under
some conditions they can be free'd. This is the same as shrinking the
dcache but instead of
We just implemented movable objects for the XArray. Let's test it
intree.

Functionality of the XArray Slab Movable Object implementation can

We just added a module that enables testing the SLUB allocators ability
to defrag/shrink caches via movable objects. Tests are better when they
are automated.
Add automated testing via a python script for SLUB movable objects.

We just implemented slab movable objects for the SLUB allocator. We

- Free objects from within specific slabs of t

Internal fragmentation can occur within pages used by the slub
allocator. Under some workloads large numbers of pages can be used by
partial slab pages. This under-utilisation is bad simply because it
wastes memory but also because if the system is under memory pressure

-M lists caches that support object migration.

that are movable (i.e. have migrate function).

It is advantageous to have all defragmentable slabs together at the
beginning of the list of slabs so that there is no need to scan the
complete list. Put defragmentable caches first when adding a slab cache
and others last.

Add the two methods needed for moving objects and enable the display of
the callbacks via the /sys/kernel/slab interface.
Add documentation explaining the use of these methods and the prototypes
for slab.h. Add functions to setup the callbacks method for a slab
cache.
Add empty functions for SLAB
Hi,
Another iteration of the SMO patch set, updates to this version are
restricted to the dcache patch #14.
Applies on top of Linus' tree (tag: v5.1-rc6).
This is a patch set implementing movable objects within the SLUB
allocator. This is work based on Christopher Lameter's patch set:
